[Abstract]:The evaluation experiment of Shimen phosphate concentrate obtained by calcination-digestion-separation is carried out. The results show that under the condition of calcium-silicon ratio 0.30and carbon content 1.5 times of theoretical amount, the burden, pelletizing, and the compressive strength of raw pellet are 34.5 N, and the ratio of calcium to silicon is 0.30 and the carbon content is 1.5 times of theoretical amount. The strength of 0.5m drop is more than 22 times, the compressive strength of dry ball is 203.5 N, the falling strength of 1 m is greater than 5.2times, and the pellet has good performance. When the ratio of calcium to silicon is 0.37, the carbon content is 1.5 times of the theoretical amount, the reduction rate of phosphorus reaches 96% at 1 360 鈩，
